为了在此网站上询问与图像相关的问题，我知道我可以按以下方式直接调用基本的非描述性图像：
\documentclass{article}
\usepackage{graphicx}
\begin{document}
\includegraphics[width=2cm]{example-image}\\
%\fbox{\includegraphics[trim=1 150 0 0,scale=0.1]{tiger}}
\end{document}
产生
然而，在某些情况下，实际图片
会更加理想。
我知道上面的老虎可以用命令来制作
\fbox{\includegraphics[trim=1 150 0 0,scale=0.1]{tiger}}
但好像这个tiger图像不能被包调用graphicx。
老虎图像以及其他类似图像是否可以通过调用某些包直接使用？我想我可以将这个经常出现在这个网站上的图像保存到我的电脑中，然后以这种方式调用它，但是，回答我发布的问题的人将无法无错误地运行我的 MWE。
问题：为了在此网站上提问，将 Latex 老虎（和类似类型的图像）纳入 MWE 的最简单方法是什么？
谢谢。
答案1
老虎是一个 ghostscript 测试 eps 文件，不是来自 latex 分布，也不在默认输入树中。
有一些图像是 ，并且会从 进行更改example-image，例如\includegraphics{pink_marble}或 \includegraphics{mill}。最后一个来自上下文，但 latex 会找到它。
texlive 输入树中 png 文件的完整列表是
for i in $(grep '\.png' $(kpsewhich --all ls-R) | sed -e 's/.*://' | sort | uniq ); do kpsewhich $i; done
显示的内容如下，显然您可以对 jpg 或 eps 执行类似操作。

答案2
图片中包含的内容不应该影响你处理解决方案的方式。你绝对可以表述问题并使用来自的示例图片mwe. 这就是所提供的美mwe（从其文档：
一旦安装在 TEXMF 树中的正确目录中，它们将可用于所有文档。这样，用户可以编译其他人提供给他的使用这些图像文件的任何 MWE，而无需替换代码或共享图像。
如果您认为图像单调且需要更多颜色，请使用pagefromexample-image-a4-numbered或example-image-letter-numbered：
\includegraphics[page=10]{example-image-letter-numbered]
还有example-grid-100x100pt和example-grid-100x100bp：
如果您想要包含“示例文档”（寻找更多文本），则有example-image-letter和example-image-letter-landscape（以及其他尺寸，如a3、a4和a5）。
在我看来，mwe包装元素可能是最常用但最少被提及的元素之一（在这个网站上），因为你不必\usepackage{mwe}为了使用图像而使用它。
作为参考，该tiger图像可在某些包位置中找到。例如，tiger.pdf从yathesis和tiger.pdf从tkz-base。因此，这些存在于 TeX 目录结构 (TDS) 中，但您必须更改\graphicspath，或直接引用它们 ( \includegraphics[..]{path/to/image/tiger})。
简而言之，使用“更理想”的图像并不能使问题变得更好。您应该能够以不需要任何特定图像（不包含在/分发给mwe）的方式提出问题。
答案3
如果您想要一个不那么无聊的图像，您可以使用该tikzlings包，例如：
\documentclass{article}
\usepackage{tikzlings}
\begin{document}
\tikz{\sloth}
\end{document}
但里面没有老虎tikzlings。
对于 tiger，可以使用.eps来包含文件的原始源代码filecontents。这里只给出大纲，以使代码更简短：
